This paper develops and applies a methodology to test for efficiency of interregional commodity arbitrage. Application of the methodology requires only time-series data on prices for alternative cities, regions, countries, or product forms. Yet, the approach is capable of generating evidence on...

A recurring concern in TOD pricing studies has been that short term experimental TOD rates may not stimulate as much conservation as would occur if TOD rates were implemented on a permanent basis. That is, how accurately do experimental TOD pricing results extend to nonexperimental settings? The...

Many important hypotheses in applied economics depend upon the magnitude of estimated elasticities or flexibilities. However, their statistical properties are unknown for many popular models, making standard statistical inference impossible. This problem is addressed in the present paper which...
